Prajanti, Anisa Dewi, Ramli, Kalamullah.  2019.  A Proposed Framework for Ranking Critical Information Assets in Information Security Risk Assessment Using the OCTAVE Allegro Method with Decision Support System Methods. 2019 34th International Technical Conference on Circuits/Systems, Computers and Communications (ITC-CSCC). :1–4.
The security of an organization lies not only in physical buildings, but also in its information assets. Safeguarding information assets requires further study to establish optimal security mitigation steps. In determining the appropriate mitigation of information assets, both an information security risk assessment and a clear and measurable rating are required. Most risk management methods do not provide the right focus on ranking the critical information assets of an organization. This paper proposes a framework approach for ranking critical information assets. The proposed framework uses the OCTAVE Allegro method, which focuses on profiling information assets by combining ranking priority measurements using decision support system methods, such as Simple Additive Weighting (SAW) and Analytic Hierarchy Process (AHP). The combined OCTAVE Allegro-SAW and OCTAVE Allegro-AHP methods are expected to better address risk priority as an input to making mitigation decisions for critical information assets. These combinations will help management to avoid missteps in adjusting budget needs allocation or time duration by selecting asset information mitigation using the ranking results of the framework.

Hong, Q., Jianwei, T., Zheng, T., Wenhui, Q., Chun, L., Xi, L., Hongyu, Z..  2017.  An Information Security Risk Assessment Algorithm Based on Risk Propagation in Energy Internet. 2017 IEEE Conference on Energy Internet and Energy System Integration (EI2). :1–6.

Traditional information Security Risk Assessment algorithms are mainly used for evaluating small scale of information system, not suitable for massive information systems in Energy Internet. To solve the problem, this paper proposes an Information Security Risk Algorithm based on Dynamic Risk Propagation (ISRADRP). ISRADRP firstly divides information systems in the Energy Internet into different partitions according to their logical network location. Then, ISRADRP computes each partition's risk value without considering threat propagation effect via RM algorithm. Furthermore, ISRADRP calculates inside and outside propagation risk value for each partition according to Dependency Structure Matrix. Finally, the security bottleneck of systems will be identified and the overall risk value of information system will be obtained.
